TERMINAL HAVING A PLATFORM LIBRARY DYNAMIC LINKING FUNCTION AND CONTROLLING METHOD FOR THE SAME

摘要

A terminal device equipped with a dynamic platform library linking function and a controlling method thereof are provided to increase dynamic linking characteristics of platform function by calling an API(Application Program Interface) after changing a real address of the platform function, as the real address of the platform function is stored in an RW(Read Write) area and is loaded to a RAM area. A non-volatile ROM modularizes platform functions located in an RO(Read-Only) area(1A) and locates a value of each modularized platform function to a stub function block(4) of an RW area(2A). A volatile RAM loads execution data and stub function block data to the RW area when the stub function block data and the execution data are received from the RW area of the ROM. A main controller(7) controls link by loading an execution program and the stub function block data located in the RW area of the ROM, finding an address value of an executed API from the stub function block, and linking the address value with the execution program. The stub function block stores real address values of the API requested from the modularized functions included in the RO area.
